      You may know physics but grammar isn’t you’re strong suit… between you and me* I is a subject, the noun that completes the action. Between two things must be between two indirect objects (me is the first person pronoun used to describe direct or indirect objects in a sentence).

      Interesting tidbit about the lunar lander. The landing gear was built by Canadian company Heroux Aerospace which is is just outside of Montreal. Since the lander was supposed to be an American success story NASA could not have something made in Canada touch the surface of the moon first. So NASA in a high tech move took a series of American made antennas from the top of the lander and strapped them to the landing gear destroying them on surface contact, but it effectively having an American made product be the first thing to "touch" the moon.

    so the term clinker actually come from smithing.. it refers to the metals found in the bottom of the forge after heating metal.. but it usually means you got the metal too hot. in short a clinker is waste metal.

    could it be plausible to use plants like algae since they convert co2 into oxygen or would this take up to much space to be effective

    I've been on submarines for 5 years and still watched this. It's quite interesting to see a civilian perspective describing it rather than the military description I learned. I already knew how the systems worked but still learned a few new facts I didn't know before. Great video.

    Can you visually detail how lithium hydroxide scrubs the co2?

  • T Ray

    I imagine there's a great deal of precision involved in off-boarding the CO2. Remaining silent, remaining undetected, are crucial to the mission so you wouldn't want escaping gas or bubbles to make a lot of noise. I'm curious if the off-boarded CO2 comes out as bubbles or if perhaps the pressure matching allows for near immediate absorption?

    This video brings back memories, I recognize that staircase, the middle level hallway, the path to the officers quarters and the fwd machinery room. I don't remember it being that small though. I was on board 688's for 4 years and the guys weren't that nice, mostly they would answer questions with go look it up yourself, might have stayed in till retirement if I had a similar experience to yours.
